NEWINGTON -- A New Hampshire Air National Guard KC-135 refueling plane landed safely at Pease International Tradeport Thursday night after tread separated on a front landing gear tire.

No one was injured in the incident

First Lt. Aaron McCarthy, executive officer of the 157th Air Refueling Wing at Pease, said the plane with a three-man crew was practicing routine touch-and-go landings about 6:15 p.m. at Manchester-Boston Regional Airport when they felt a vibration and suspected they had a blown tire.

Immediately, they called an in-flight emergency and returned to Pease where the plane made a low-level approach with the landing gear down so a supervising pilot on the ground could try to make a visual inspection of it. The pilot could not see anything and the plane, piloted by Lt. Col. Robert Courtemanche, made a soft, uneventful landing.

The KC-135 taxied to the end of the runway where the maintenance crew inspected the landing gear and discovered the tread separation on a front landing gear tire. McCarthy said there was some tire left.

The incident is under investigation, according to McCarthy.
